heal.abstract	La0.8Sr0.2MnO3-δ was synthesized by the Pechini's method. The XRD pattern and TEM indicate the formation of the perovskite without the presence of secondary phases. It was found that La0.8Sr0.2MnO3-δ sample prepared at 1000 °C in air atmospheres, contains about 13.11% of the manganese as Mn4+ and 86.89% of the manganese as Mn3+. The electric measurements were carried out for La0.8Sr0.2MnO3-δ nanoceramics by using impedance spectroscopy methods and found to be 0.1 S/cm at 250 °C similar to the typical value of La0.8Sr0.2MnO3-δ materials. Its dependence on reciprocal temperature shows quite complicated mechanism of conduction. © 2009 The Chinese Society of Rare Earths.	en
